Direct answer: DVSA’s latest national table for April 2025 to March 2026 ranks junction observations first, mirrors when changing direction second and right-turn positioning third. It covers car tests in England, Scotland and Wales and identifies common failure areas—not ten automatic-fail rules or a prediction of your route.

What the latest DVSA ranking covers

The newest official evidence is DVSA table DRT121F, published on 25 June 2026 with data for the financial year from April 2025 to March 2026. It is a national Great Britain ranking of the ten most common car-test fault areas. The scope is England, Scotland and Wales; Northern Ireland tests are administered separately by the Driver & Vehicle Agency.

DVSA’s illustrated ‘Top 10 reasons’ web page still shows the earlier April 2024 to March 2025 order. Its practical examples remain useful, but the newer statistical table should be used for the latest ranking. This guide combines the current order with those official explanations and result guidance.

The spreadsheet publishes ranks and category names, not counts or percentages. A candidate can record faults in more than one area, so the table cannot support claims such as ‘a particular percentage of learners fail for junctions’. Use it to prioritise preparation, not to calculate your personal chance of passing.

The latest top 10 at a glance

These are the categories in DVSA’s 2025–26 order. The wording after each dash is the fault-area label you may recognise from a test result or mock-test report.

Not making effective observations at junctions — Junctions: observation.
Not using mirrors correctly when changing direction — Mirrors: change direction.
Incorrect positioning when turning right — Junctions: turning right.
Not responding correctly to traffic lights — Response to signs: traffic lights.
Not controlling the steering properly — Control: steering.
Not moving off safely — Move off: safely.
Not responding correctly to road markings — Response to signs: road markings.
Not responding correctly to traffic signs — Response to signs: traffic signs.
Poor positioning during normal driving — Positioning: normal driving.
Not maintaining progress at an appropriate speed — Maintain progress: speed.

What changed since 2024–25

Junction observations and mirror use remain first and second. Right-turn positioning moved from fourth to third, traffic lights from fifth to fourth and steering control from sixth to fifth. Moving off safely fell from third to sixth. Road markings, traffic signs and normal road position remained seventh, eighth and ninth.

The important change at number ten is the type of speed fault. The 2024–25 illustrated list used ‘Use of speed’, which concerns driving too fast, exceeding a limit or failing to reduce speed for conditions. The newer table uses ‘Maintain progress – speed’, which concerns driving unnecessarily slowly or holding up traffic when conditions allow reasonable progress.

That does not make a speed limit a target. A lower speed can be necessary on a narrow road, near vulnerable road users, in poor weather or when visibility is limited. The skill is choosing a safe, lawful and reasonable speed for the situation rather than aiming at one number.

Junction observations and mirrors: decisions, not rituals

At junctions, an effective observation happens early enough to affect the decision. Looking without judging the speed and distance of an approaching vehicle is not enough. Practise minor-road exits, roundabouts, crossroads and slip roads on unfamiliar routes, and ask your instructor to record when a prompt or intervention was needed rather than whether your head appeared to move.

Mirror checks work the same way. Use the relevant mirrors before signalling, changing lane or direction, and act on what you see. A late glance after the car has started moving does not create a safe gap. DVSA does not require exaggerated head movements; the check needs to be timely and effective.

A useful lesson review is to identify the decision behind each mark: what did you need to know, when did you need to know it, and what safe option was available? That builds a repeatable observation routine instead of a performance designed only to look correct to an examiner.

Right turns, traffic lights, steering and moving off

The next four categories test different parts of planning and control. Practising them together helps reveal whether a positioning or steering problem begins earlier with observation, speed or lane choice.

Right turns: select the correct lane in good time and, where safe, position close enough to the centre of the road to show your intention without unnecessarily obstructing following traffic.
Traffic lights: respond to red and amber signals, stop before the correct line, keep cycle areas clear and do not enter a blocked junction simply because the signal is green.
Steering: steer smoothly and at the right time so the car follows the road, maintains clearance and does not swing into the wrong side of a new road. Assessment is about control, not one prescribed hand routine.
Moving off: make all-round observations, include the relevant blind spot and wait if moving would force another road user to slow or stop. Practise level, hill and angled starts in varied traffic.

Markings, signs, road position and maintaining progress

These four areas depend on reading the road early enough to make an unhurried choice. If you realise you are in the wrong lane, continue safely rather than making an abrupt correction just to follow the requested route; taking a wrong direction is not itself a fault when handled safely.

Road markings: follow lane arrows, mini-roundabout markings, box-junction rules and solid white-line restrictions. Scan far enough ahead to choose a lane before the last moment.
Traffic signs: recognise stop, no-entry, keep-left, timed bus-lane, speed-limit and lane-direction signs, then adjust before reaching them rather than reacting after passing them.
Normal position: keep a stable lane position with safe clearance, avoid drifting too close to the kerb or centre line and return to the left lane of a dual carriageway when appropriate.
Maintaining progress: use an appropriate speed when the road is clear, while reducing it whenever traffic, visibility, weather, road width or hazards require. Safe progress is neither rushed nor unnecessarily hesitant.

What the ranking does not mean

The top ten is not a list of automatic fails. The examiner records the severity of what actually happened: a driving fault is below the expected standard but does not fail the test by itself, while a serious fault is potentially dangerous and a dangerous fault creates actual danger. The same report heading can therefore contain incidents of different severity.

It is also not a route guide, a test-centre ranking or proof that skills outside the ten are unimportant. Your test can include a fault area that is not on this national list, and manoeuvres, independent driving, vehicle-safety questions and the eyesight check still form part of the assessment.

For the numerical rule, you can pass with no more than 15 driving faults only if there are no serious or dangerous faults. The dedicated fault-count and fault-classification guides linked below explain that standard without turning this ranking into a scoring shortcut.

Turn the list into a focused practice plan

Start with evidence from lessons, a mock test or a previous result. Record the official fault heading, the situation in which it appeared and the decision that would have prevented it. A heading such as ‘Junctions – observation’ becomes useful only when you know whether the cause was looking late, misjudging speed, approaching too quickly or failing to act on what you saw.

Then practise the underlying decision on varied roads rather than repeating one familiar test route. Remove prompts gradually and finish with a realistic mock test so the skills must work together under normal test conditions. Review repeated patterns before isolated imperfections.

Diagnose: ask your instructor to mark a mock drive against the official assessment areas.
Isolate: practise one weak decision in several safe and different situations.
Combine: use ordinary drives to link observation, planning, speed, position and control.
Retest: complete a mock drive without prompts and compare the new pattern with the first record.
Decide: take the test when your driving is consistently independent and your instructor agrees you are ready.

Use the result constructively

If you do not pass, read the result by fault heading rather than labelling the whole drive a failure. Deal with every serious or dangerous fault first, then look for a repeated driving-fault pattern. Ask the examiner’s explanation and your instructor’s observations to be connected to a specific practice task.

Rebooking quickly does not correct the underlying skill. A stronger sign of readiness is that you can make the safe decision on unfamiliar roads, without a prompt and while managing the rest of the drive.
